I'm having the same issue. I didn't find anything in Windows Event Service's logs. I tried to change mysql port from 3306 to 33061 but it didn't helped. The logs even say that its trying to use 3306 still!Thanks in advance!The following are some debug info.

--- BEGIN of my.ini MYSQL's configuration file ---# Example MySQL config file for small systems.## This is for a system with little memory (<= 64M) where MySQL is only used# from time to time and it's important that the mysqld daemon# doesn't use much resources.## You can copy this file to# C:/xampp/mysql/bin/my.cnf to set global options,# mysql-data-dir/my.cnf to set server-specific options (in this# installation this directory is C:/xampp/mysql/data) or# ~/.my.cnf to set user-specific options.## In this file, you can use all long options that a program supports.# If you want to know which options a program supports, run the program# with the "--help" option.

# The following options will be passed to all MySQL clients[client] # password = your_password port = 33061socket = "C:/xampp/mysql/mysql.sock"

# Where do all the plugins liveplugin_dir = "C:/xampp/mysql/lib/plugin/"

# Don't listen on a TCP/IP port at all. This can be a security enhancement,# if all processes that need to connect to mysqld run on the same host.# All interaction with mysqld must be made via Unix sockets or named pipes.# Note that using this option without enabling named pipes on Windows# (via the "enable-named-pipe" option) will render mysqld useless!# # commented in by lampp security#skip-networking#skip-federated

# required unique id between 1 and 2^32 - 1# defaults to 1 if master-host is not set# but will not function as a master if omittedserver-id = 1

# Replication Slave (comment out master section to use this)## To configure this host as a replication slave, you can choose between# two methods :## 1) Use the CHANGE MASTER TO command (fully described in our manual) -# the syntax is:## CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;## where you replace <host>, <user>, <password> by quoted strings and# <port> by the master's port number (3306 by default).## Example:## CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,# MASTER_USER='joe', MASTER_PASSWORD='secret';## OR## 2) Set the variables below. However, in case you choose this method, then# start replication for the first time (even unsuccessfully, for example# if you mistyped the password in master-password and the slave fails to# connect), the slave will create a master.info file, and any later# change in this file to the variables' values below will be ignored and# overridden by the content of the master.info file, unless you shutdown# the slave server, delete master.info and restart the slaver server.# For that reason, you may want to leave the lines below untouched# (commented) and instead use CHANGE MASTER TO (see above)## required unique id between 2 and 2^32 - 1# (and different from the master)# defaults to 2 if master-host is set# but will not function as a slave if omitted#server-id = 2## The replication master for this slave - required#master-host = <hostname>## The username the slave will use for authentication when connecting# to the master - required#master-user = <username>## The password the slave will authenticate with when connecting to# the master - required#master-password = <password>## The port the master is listening on.# optional - defaults to 3306#master-port = <port>## binary logging - not required for slaves, but recommended#log-bin=mysql-bin

# Point the following paths to different dedicated disks#tmpdir = "C:/xampp/tmp"#log-update = /path-to-dedicated-directory/hostname

# Uncomment the following if you are using BDB tables#bdb_cache_size = 4M#bdb_max_lock = 10000

Just noticed that mysql_error.log file was not being updated.When I start mysql server from command line, mysqld.exe, it all goes fine and even XAMPP Control Panel detects it! Just not working the mysql server start command from the XAMPP Control Panel.
